Abstract Scope |
A novel FCC austenitic steel with high strength is under development for potential structural applications. The high strength is primarily achieved through precipitation of nanoscale vanadium carbides. The heat affected zones in welded material has recently been assessed using both Gleeble simulated thermal cycles and gas tungsten arc welds. The morphology and distribution of the carbides was determined in 3D using atom probe tomography. The relationship between the carbide distribution and the peak temperatures reached and the processing history in the heat affected zones will be discussed, as well as compared with the local mechanical properties and computational predictions from ThermoCalc. |
